HT Instruments Flashmeter Digital Multimeter, Waterproof (IP67), CAT IV 600V, 4000 Counts, True RMS 1010605

Electrical measurements in wet or dusty environments demand a tool that won't fail when conditions get tough. The HT Instruments Flashmeter is a waterproof digital multimeter built to keep working where standard meters can't, with an IP67 rating that protects against immersion and dust ingress. Its CAT IV 600V safety rating means you can confidently test at the source of low-voltage mains installations.

Who is it for

Electricians and maintenance technicians who work outdoors, in industrial settings, or anywhere that moisture and debris are a constant threat. If you need reliable readings in challenging conditions, this meter is built for you.

Main features

• Waterproof and dustproof: IP67-rated housing withstands temporary immersion and keeps out fine particles.
• High safety category: CAT IV 600V / CAT III 1000V for safe testing at the distribution level.
• True RMS measurement: Accurate readings on non-sinusoidal waveforms from inverters and variable-speed drives.
• 4000-count display: Clear LCD with auto-ranging for quick, precise measurements.
• Full multimeter functions: AC/DC voltage, AC/DC current, resistance, capacitance, frequency, temperature (K-type thermocouple), diode test, and continuity with buzzer.
• Data hold and min/max: Freeze readings and capture peaks for later review.
• Powered by a single 9V battery (6F22).
